Answer:
Step-by-step explanation:
Given that there are two vectors U = (-8,0,1)
V = (1,3,-3)
To find projection of u on V and also projection of V on U
First let us find the dot product U and V
U.V = 
Projection of U on V =
Similarly projection of V on U
=
11/100, easy. Unless you want something more complicated?
Answer:
x = 15
Step-by-step explanation:
These angles are supplementary so you'd set up an equation like 3x -15 +150 = 180 then solve for x from there.
